G312323329 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=100mm 1064nm

This is a Plano-Convex lens, sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens, identified as G312323329, has a diameter of 25.4 mm and a thickness of 2.4 mm at the edge, which graduates to 4 mm at the center. The effective focal length (EFL) of this lens is 100 mm, making it suitable for a variety of optical applications, particularly those involving the wavelength of 1064 nm.

The lens is made of N-BK7, a popular type of borosilicate glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it an ideal choice for many optical systems. The lens's geometry is spherical, with a radius of curvature of 51.21 mm on the convex side. The inner and outer radii are both zero, indicating a plano surface on the other side.

The lens features anti-reflective coatings on both the front and back surfaces. These coatings, identified as Qio HP Nbar Arhs-Yag, are specifically designed to reduce reflection and increase transmission at the wavelength of 1064 nm. This makes the lens more efficient and ensures that more light passes through it, which is crucial in many optical applications.
